TP Link Tapo S500 smart Wi Fi light switches stand out as a solid way to add app, voice, and Matter based control to existing lights, especially when the box already has a neutral wire. Setup can be quick in a compatible install, and the switches keep working as regular manual switches during internet outages, with local app control still available on the home network. The main cautions are older homes, where box space, thick wiring, or missing neutral wires can complicate installation, and the dimmer version can flicker with LED bulbs. A practical pick if your wiring is ready and you want simple smart control.

  • people setting up Apple Home first for Matter-style workflows because you need to enable it via Apple Home before using the Tapo app (and the HomeKit-first setup steps worked for at least one buyer).

  • buyers replacing multiple existing switches in a room because commenters reported successfully swapping many switches (Kasa to Tapo) and getting them working well.

  • homeowners who already have neutral wires in the switch box because installation can be a quick ~5 minute job.

  • households that want smart control but still need reliable manual operation during internet outages because the switches still work as a regular light switch even when Wi‑Fi/internet is down.

  • people installing dimmable LED lighting because the dimmer version was reported to work well with dimmable LEDs and includes a calibrate function.

  • renters or homeowners who want to control lights from their phone even if the internet drops because local control via the Tapo app can still work when the internet is down but in-house Wi‑Fi is active.

  • older-home owners because you may not have enough box space for the switch even if it physically fits, and there can be code considerations.

  • people with older wiring setups that lack a common wire because a common wire is required and many older houses don't have it.

  • buyers who don't want to deal with wiring friction because one commenter had to use bigger wire caps than provided due to old, thick, non-malleable wires and recommended having pliers (and possibly a wire stripper).

  • people who specifically want Matter-certified devices because the switches were described as not "Matter" certified, which may reduce future-proofing across ecosystems.

  • buyers using LED bulbs that are sensitive to dimming because the dimmer version caused LED bulb flicker for at least one user.

  • people who prefer an up/down rocker feel because one commenter didn't like the toggle-style operation where on/off is only one-way press.

  • buyers who need Home app reliability because one commenter couldn't get the Home app to work and switched to using Alexa instead.

  • people planning multi-switch gang box installs without extra parts because the switches only include one unit faceplate and multi-switch gang boxes can get tight, requiring additional faceplates.

and do these still work during an internet outage?
Yes, they do work. It shows up as a white ring when its connected. If there is an outtage the white ring turns into red.

You can also turn off the ring (via their app)

I have never been able to make the Home app work. I gave up. Just Alexa for now.
Try below. This is what worked for me.

Method 2: Apple HomeKit First

Factory Reset: Physically reset the Tapo switch (press and hold the power button for about 10 seconds until it flashes orange/blue).
Add to HomeKit First: Open the Apple Home app and add the switch using its QR code or numeric code, completing setup in the Home app first.
Link in Tapo App: After it's in HomeKit, you can then add the device to the Tapo app for full Tapo features

I have at least half a dozen of these and another half dozen of the dimmer version installed (all the previous version/model), and they all work really, really well. The app is needed to set them up and should be used after setup if you want to set schedules like sunrise-sunset or just control them from a smartphone. 2.4G wifi only. Works well with dimmable LED lights designated as being "dimmable" (has a calibrate function for those). This and and dimmer ones at 4 for $45 (which I just ordered) are a real deal. Hope this new model works as well as the ones I already have.

If your house is relatively modern and has a proper electrical system wired by a licensed contractor, I have heard you can tie the neutral wire on these to ground and these will work. This is NOT intended as actual advice, but that's what I've read.

This is cloud data center controlled right?

Have to have the app that talks to a server in a cloud data center which then sends the command to your switch, right?

Not directly home assistant controlled in your own home network. For that you need support for matter protocol in the device.

I know some have reverse engineered the commands the server in the cloud sends and have HA send it. Is that the case here?
My experience using the TAPO app has been that if the Internet goes down but your in-house wifi is active, these will continue to work with the app. It was something of a surprise. I don't know if scheduling etc. works, but you can turn the lights on and off and dim them from your phone (the previous generation of the switches, which is what I have). From the Amazon page: "Local Control...Your connected devices at home stay accessible via the Tapo app even when your household is offline."

The dimmer ones make my light flicker with led bulbs
LED bulbs have to be designated as "dimmable", and it helps to run the app's calibration sequence one time on LEDs after installation. I have AT LEAST twenty LEDs being dimmed by these, and not one of them flickers.

A relatively modern house will have a neutral in the switch box. Using a ground wire for anything other than grounding is a code violation.

I put these throughout the house - they work well but the app kinda sucked for setup. It's been easy since then though.

honestly this one with Matter was easier than I thought. I didn't have to use the TP link app at all, just scanned the QR code with the camera and it pulled it up on the Home app right away. just 2 steps to confirm.
